Abstract (en)
[origin: EP3228463A1] In accordance with an embodiment, an ink circulation device comprises an ink supply section, an ink return section, an ink circulation pump, a filter and a bypass section. The filter partitions an upstream side ink flow path arranged between an ejection section of the ink circulation pump and the ink supply section into a first flow path communicating with the ejection section of the ink circulation pump and a second flow path communicating with the ink supply section. The bypass section is arranged at the upper part of a vertical direction with respect to the filter, directly communicates the first flow path with a downstream side ink flow path arranged between the ink return section and a suction section of the ink circulation pump. An inkjet recording device of the present embodiment comprises the foregoing ink circulation device.
